Finite energy sum rules for vector and axial-vector currents are derived in a
thermal medium in order to provide constraints for the spectral behavior of rho
and a1 mesons at non-vanishing temperature and hence to study the tendency
toward chiral symmetry restoration. The parity mixing ansatz for the rho and a1
spectrum, including finite widths, is investigated as a function of
temperature. Characteristic differences between vector and axial-vector
channels are discussed concerning the implementation of the chiral symmetry
breaking scale, 4 pi times the pion decay constant, in the sum rule approach.
